Complete and balance the single replacement reactions: (c) silver bromide, AgBr WebThe potentiometric titration of chloride, bromide, iodide and thiocyanate with silver nitrate, using the mineral pyrite as a sensor for the detection of the end-point, is described. Sodium nitrate is also soluble in water so after the reaction has occured, sodium and nitrate ions are still floating in solution. (a) A soft, gray piece of lithium is added to water The precipitate will be silver bromide, as long as the solutions For example: It is more difficult to explain the reason for this, because it needs a fairly intimate knowledge of the mechanisms involved in the reactions. An exothermic reaction is indicated by writing + Heaton the products side of an equation. For chloride Cl-ions, sodium chloride (NaCl) reacts with s ilver nitrate (AgNO 3) and forms sodium nitrate (NaNO 3) and a white precipitate of silver chloride (AgCl).
